What to expect in the real world

On quality pump fuel with the right supporting mods and a proper remap:

• E chassis N55 (2011 to 2013) on 93 octane or 99 RON. Commonly 430 to 480 whp with intercooler, downpipe, charge pipe, upgraded low pressure fuel pump and custom tuning
• F chassis N55 (2012+) on 93 octane or 99 RON. Commonly 430 to 450 whp with intercooler, downpipe, charge pipe and a custom map. For 450+ whp, an upgraded high pressure fuel pump is recommended

Well set-up builds have recorded 520 to 536 whp on the dyno. Figures will vary with fuel quality, hardware selection, engine health and calibration.
